Sources close to the event today told MMAjunkie.com (www.mmajunkie.com) that the British lightweight is expected to meet Evan Dunham (12-2 MMA, 5-2 UFC) at UFC on FOX 2. ESPN.com initially reported the fight.

UFC on FOX 2 takes place Jan. 28 at United Center in Chicago. A light-heavyweight bout between former champ Rashad Evans and Phil Davis is expected to headline.

The night’s main card airs live on FOX while preliminary fights air on FX and FUEL TV. It’s not clear where Dunham vs. Sass will be situated on the card.

Sass kept alive an incredible and almost unbroken streak of submission victories with a first-round heel hook of Michael Johnson at UFC on Versus 6. That built on his octagon debut at UFC 120 in which he tapped out Mark Holst by first-round triangle, his eighth such win by that choke.

Only two of Sass’ 12 professional foes have made it out of the first round.
